The Blick Art store on Bond street has a sale through October 9th on brushes. Windsor & Newton Series 7 brushes are 50% off.

For those who never used one, these brushes (Kolinsky sable) are to painting what doorknobs are to going through doors. Read what Ryan says about em. They usually run about $16, so 50% off is a good deal.

Bond Street is between Lafayette and Broadway down by the Broadway-Lafayette subway station (F Train). I'm not planning to go--I usually try to avoid Manhattan as much as possible.

Also you may not need a couple of brushes--I bought one #1 size more than a year ago, took care of it as Ryan specified (no metallics, no inks) and it's still in perfect condition. One brush could theoretically last a really long time, and the needle point of the #1 brush is fine enough to paint everything except maybe eyeballs.
